Answer:
8/17
General Formulas and Concepts:
<u>Trigonometry</u>
- [Right Triangles Only] cos∅ = adjacent over hypotenuse
Step-by-step explanation:
<u>Step 1: Define</u>
We are given a right triangle. We can use trig to find the ratio.
<u>Step 2: Identify</u>
<em>POV from angle S</em>
Adjacent = 8
Hypotenuse = 17
<u>Step 3: Write</u>
- Substitute [cosine]: cos(s) = 8/17
Answer:
uuh The a is equal to 16
Step-by-step explanation:
Answer:
13
Step-by-step explanation:
|-20| = 20 (anything with | | is absolute value, which is always positive), |7| = 7, 20 - 7 = 13.
quick tip: when you see something like -|#|, that would be negative, but if you saw |-#|, it would be positive.
hope it helps lol
D + q = 35....d = 35 - q
0.10d + 0.25q = 6.50
0.10(35 - q) + 0.25q = 6.50
3.50 - 0.10q + 0.25q = 6.50
-0.10q + 0.25q = 6.50 - 3.50
0.15q = 3
q = 3 / 0.15
q = 20 <=== 20 quarters
d + q = 35
d + 20 = 35
d = 35 - 20
d = 15 <=== 15 dimes
